'BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 561,133, dated June 2, 1896. Application filed March 19, 1895. Serial No. 542,416. (No model.)

To all whom it may concern.-

Be it known that we, AMos'Ro0P, FRANCIS L. BRANDON, and JOHN S; HART, citizens of the United States, residing at Hicksville, in the county of Defiance and State of Ohio, have inventedanew and useful Baling-Press, of which the following is a specification.

Ourinvention relates to baling-presses, and has for its object to provide an improved con struction of double press, having duplicate baling-chambers in which separate bales are formed at the same time by a single plunger, which moves alternately in opposite directions and which compresses the hay in the chamber toward which it moves; to improve and strengthen the construction of the plunger-boX and baling-chambers to secure the requisite strength with the minimum weight; to provide means for securing the desired pressure of the sides of the baling-chambers upon the follower-blocks to regulate the compactness of the bales; to provide new and efficient means for communicating motion from the driving-shaft to the plunger, and to provide efficient shifting or reversing mechanism, operated by the plunger, to change the direction of movement of thelatter at the limits of its strokes, such reversing mechanism being independent of the power by which the press is operated, whereby. the drivingshaft may rotate continuously in a uniform direction.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will. be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective View of a baling-press constructed in accordance with our invention. Fig. 2 is aside view showing the opposite side of the press from that which is indicated in Fig. 1. Fig.

V Fig. 4. is a transverse section on the line 4. 4. of Fig. 3. Fig. 5 is a horizontal section on the line 5 5-of Fig. 3, showing the gearing in plan. Fig. 6 is a detail plan view of the outer end of one of the baling-chambers, partly in section, to show the means for regulating the tension of the side bars by which the movement of the follower-blocks is regulated. Fig. 7 is a detail view of the clutch by which the shifting or reversing bar is held in place during the return movement of the follower-block. Fig. 8 is a vertical section on the line 8 8 of Fig. 2.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

Upon trucks 1 and 2, having supportingwheels 3, is mounted the framework of the improved press, having a central plungerbox 4 and opposite alined baling-chambers 5, the sides of said plunger-box and balingchambers being constructed of continuous metal bars 6, spaced apart to form intervening slots or.openings 7 in the sides of the baling-chambers and being held at the desired intervals by spacing or filling blocks 8 in the sides of the plunger-box, whereby the sides of the latter are solid or continuous with the exception of central horizontal slots 9. It willbe understood that the sides of the plunger-box may be constructed with the spacing-blocks S integral with the bars; but the above-described construction is preferable, for the reason that it simplifies and reduces the cost of manufacture. Transverse blocks 10 are secured to and connect the upper edges of the sides of the plunger-box, and between the inner edges of these blocks is seated the hopper 11, forming a part of an automatic feed mechanism hereinafter more fully described.

The upper and lower sides of the balingchambers are sectional in construction, each consisting of duplicate side sections 12 and 13, provided with rabbeted overlappin g inner edges, as shown at 14., and connected at their inner ends by cleats 15, which are secured thereto by means of bolts 16, thus providing forlateral swinging movement of the outer ends of the sections. Upper and lower transverse cleats 17 connect the outer ends of the sections of the tops and bottoms of the baling-chambers, pins 18, which are secured to and carried by said sections, being arranged to operate in slots 19, formed in the cleats. The outer or lateral edges of the sections 12 and 13 are flanged, as shown at 20, to bear against the outer surfaces of the uppermost and lowermost bars of the sides of the balingchambers, and the tops and bottoms are con- 7 nected at their inner ends by means of vertical'straps 21. The transverse cleats 17 at ICO the outer ends of the baling-ehambers are extended beyond the planes of the sides of the chambers, and in bearings 22, formed in such extensions, are mounted the reduced spindles 23 at the upper and lower ends of the eccentric rollers or cams 24, and stiffening-ribs 25 are formed on the outer surfaces of the bars (3, the outer surfaces of such stiffening-ribs being in planes corresponding with the outer surfaces of the flanges 20, whereby the surfaces of the eccentric or cam rollers 24; bear against said flanges and: rib and provide for the inward adjustment of the outer extremities of the sides of the baling-chambers when said eccentric or cam rollers are rotated. The upper ends of the eccentric or cam rollers are fitted with ratchet-wheels 26, which are engaged by pawls 27 to hold said parts at the desired adjustment and cause the required frictional contact of the inner surfaces of the sides with the follower-blocks 28, (shown in Fig. 3,) which operate in the baling-chamhers and are arranged between the bales.

The plunger 29 operates in the plunger-box i and is provided with lateral arms 30, which operate in the longitudinal slots 9 in the sides of said box, said arms terminating in nuts 31, having threaded openings 32, with which are engaged the worms or screw-bars 33, having reduced journals 3%, mounted in bearings upon the outer sides of the plunger box. These worms or screw-bars are provided at corresponding ends with chain wheels 36, traversed by a chain 37, which also passes around a master chain-wheel 38, located below the plane of the plunger-box and secured to a longitudinally-disposed shaft 39, which is mounted in bearings and 40 in a pendent frame 41, said frame comprising hangers 42, connected at their lower ends by trans verse bars 43. The bearing 40 is formed in a bearing-block 44:, which is mounted to slide transversely in the frame 41, whereby the pinion 45, also carried by the shaft, may be caused to mesh with a pinion 46 on a longitudinal shaft 47 or a pinion 48 011 a similar shaft 49, said shafts 4:7 and at!) being mounted in permanent bearings also formed in the frame atl. The intervals between the shaft 39 and the shafts 47 and 49 are such as to prevent the pinion from meshing with both of the pinions 46 and 4S simultaneously, and a spring 50 is employed to normally hold the pinion 45 in engagement with the pinion 46. The shafts l7 and &9 are provided at one end with intermeshing gears 51 and 52, whereby motion communicated to the gear 51 causes an opposite rotation of the gear 52, irrespective of the position of the pinion 45.

A longitudinal shaft 53 is mounted in bearings 54: on the pendent frame and is provided at one end with a gear 55 to mesh with the gear 51 and at the other end with a pinion 56, which meshes with a horizontal crown-gear 57, mounted upon a vertical spindle 58 and receiving motion from the driving -shaft 59 through a pinion 60.

The inner end of thedriving-shaft is mounted in a bearing in the upper extended portion ofthe spindle 58, and adjacent to the periphery of the horizontal gear 57 said shaft is mounted in a bearing (51, formed in a swinging frame 62, mounted coaxially with the horizontal gear. The chain 37 passes around direction pulleys U3, arranged below the plane of the bottoms of the baling-ehambers.

From the above description it will be seen that motion communicated to the gear from the driving-shaft will cause continuous rotation of the shafts 47 and 49 in a uniform direction, said shafts 47 and -l9,however, turnin g in relatively opposite directions, whereby when the shaft 39 receives its motion from the shaft 47 it will turn in one direction, thus actuating the worms or screw-bars in a given direction, and when said shaft receives motion from the shaft 49 it will be turned in the opposite direction, thus rotating the worms or screw-bars in the opposite direction to that caused by the first-described adjustment of parts.

In order to secure a reversal of the rotation of the worms or screw-bars at the ends of the strokes of the plunger, we employ a shifting or reversing bar til, mounted to slide in keepers 65, a rock-sha ft (56, mounted in bearings (57 and (58 on the frame 4-1, a connecting-rod 69 between the crank-arm on the lower end of said rock-shaft and the shaft 39, and a connecting-rod 71 between the reversing or shiftin g bar and the upper crank 72 of said rockshaft. The reversing or shifting bar is provided near one extremity with a detent or shoulder 73, which is arranged in the path of one of the arms of the plunger, and near the other end of said bar is arranged a clutch 74, which is adapted to engage the shifting bar when it is moved in the direction indicated by the arrow in Fig. 2 and prevent return movement or movement in the opposite direction until the trip-arm 75 at the lower end of said'cluteh is engaged by the arm of the plunger. The spring 50, which is above described as being employed to hold the shaft 39 in such position as to cause the pinion 45 to mesh with the pinion i6, serves to return the shifting bar and connected parts to their normal positions after having been moved in the direction of said arrow in Fig. 2,andt-]1erefore it is against the tension of this spring that the clutch holds the shifting bar after the latter has been moved in the direction of the arrow at the end of the movement in one direction of theplunger. The clutch is provided with an opening 76, through which the shifting or reversing bar extends, and the upper and lower sides of this opening bite the upper and lower surfaces of the rod to prevent return movement of the same until the clutch has been tripped. In order to vary the position of the detent or shoulder of the shifting bar, and thereby vary the point at which the gearing is shifted to cause reverse movement of the worms or screw-bars, the upper IIO bearing 67 of the rock-shaft is slotted longitudinally, as shown at 77, and said slot is engaged by a bolt 7 8, as shown in Fig. 2.

Fulcrumed within the hopper, which communicates with the top of the plunger-box, is a packer 79, having wings 80, arranged perpendicular to each other,and the means for operating this packer consist of levers 81, connected to lateral studs carried, respectively, by the wings and fitted to slide in guides 82 on the sides of the plunger-box. The said studs operate in arc-shaped slots 83 in the sides of the hopper, and the lower ends of the levers are arranged in the paths of the lateral arms of the plunger.

The construction of the packing mechanism above referred to is particularly described and claimed in Patent No. 543,632, granted to us on July 30, 1895. V I V The guides in which the levers operate provide sliding fulcrums, and as the plunger reciprocates in the plunger-box the lower ends of the levers are alternately engaged by the lateral arms, thus communicating an oscillatory motion to the packer which feeds the hay, cotton, or other material into the plunger-box in front of the plunger.

The detents 84, which are arranged at opposite sides of the baling-chambers, and at their inner ends, are connected by spindles 85, mounted in bearings 87 on the exterior surfaces of the chambers, and the detents extend through the pinions or slots in the sides of the chambers with their inner ends in the path of the plunger. Said spindles are provided at their upper ends with arms 88, to which are connected actuating-springs 89 to normally hold the detents in the path of the plunger and yield when the detents are engaged by the plunger and are swung laterally in to the slots or openings. The plunger is provided adjacent to its faces with cavities 90, whereby as the plunger recedes, after having advanced into a chamber, the detents of said 'baling-press, the operation thereof, briefly stated, is as follows: Motion is communicated from the driving-shaft through the pinions and horizontal gear to the longitudinally-disposed shaft 53, and from the latter through the intermeshing gears to the shafts 47 and 49, which are thus rotated in opposite directions. The shaft 39, which is arranged between the oppositely-moving shafts 4'7 and 49, carries a gear (in this case consisting of a chain-wheel) from which motion is communition.

pinion which is adapted to mesh with a pinion carried by the shaft 47 or a similar pinion carried by the shaft 49, whereby the shaft 39 may receive motion in either direction to communicate motion in either direction to the worms or screw-bars. WVhen the plunger reaches the limit of its movement in the direction indicated by the arrow in Fig. 2, the lateral arm thereof engages the detent or shoulder on the shifting bar and moves said bar in the same direction, thereby partly turning the rock-shaft and drawing the pinion on the shaft 39 into engagement with the pinion on the shaft 49, thereby reversing the direction of rotation of the shaft 39 and communicating a reverse rotation to the worms or screw-bars. Said shifting bar is held in this position after being shifted by the arm of the plunger, and hence the plunger is advanced in the opposite direction to that in which it was moving when the detent or shoulder was engaged thereby. When the arm of the plunger encounters the trip-arm forming a part of the clutch at the opposite limit of movement of the plunger, said clutch is disengaged from the shifting bar, which it previously held in the position desired against the tension of the spring 50, and allows said bar to resume its normal position, to which it is returned with the intermediate connected parts by said spring, whereupon the direction of rotation of the worms or screw-bars is again reversed and the plunger advances in the opposite direction. Each advance movement of the plunger causes an oscillation of the packer, thus feeding the hay, cotton, or other material into the path of the plunger to be pressed into a baling-chamber. The eccentric or cam shafts by which the freeends of the sides of the baling-chambers are adjusted may be turned by means of a wrench or lever, (not shown,) for which purpose the upper ends-of the spindles are constructed to form wrench-seats.

It will be understood that in practice various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
